This tutorial provides a comprehensive guide on creating timelock smart contracts, which are designed to restrict certain functionalities within a smart contract to a specific timeframe. Commonly applied in scenarios such as initial coin offerings and vesting schedules, timelock contracts can also serve as a digital will that activates upon verification of a death certificate. The focus of the tutorial is on developing an ERC-20 contract that uses a timelock queue for minting tokens, utilizing the Foundry toolset for building and testing. It introduces key concepts such as generating transaction hashes, manipulating blockchain timestamps to simulate time passage, and ensuring contract integrity with tests that prevent misuse like double queueing or premature minting. The tutorial also highlights the potential for integrating Chainlink Automation to automate function executions within smart contracts, enhancing efficiency and reducing the risk of missing execution windows.
